Abstract


In the approximation of Sobolev and paraxial optics methods, the focusing effect of a complex gravitational lens formed by the gravitational fields of a macrolens-galaxy and a microlens-star was analyzed. The problem is solved for an arbitrary location of the microlens along the source – macrolens – observer route. Intensity contours of images were constructed and magnification factor of a complex lens was calculated. It was shown that the microlens renders the greatest influence on the focusing effect when it is located on the macrolens – observer route. The obtained results can be used in solving the inverse problem of parameters recovery of dark matter by observing the microlensing effect.
